I think what this guy is trying to say, the artists are the same so some of the reactions will look the same. Also, Kora and Aang have the same spirit so they should have some of the same reactions and faces.

You are seriously talking out of your ass... the only recycled aspect of the PLOT, is that people are being threatened by another group. I don't think you understand what plot means, if you claim that similar scenes and similarities between characters show a recycled plot. Furthermore, I think you are 13. No real evidence, but that's the feeling I am pulling from you. Just saying.

No, you obviously never watched either Avatar series "with a sharp eye." The first three are only showing similar facial expressions because...well they are kind of the same person reincarnated. The last one is Aand leaving Katara, but he comes back. In Korra she doesn't come back and is leaving for good. So they are not even close to being similar. The point was to show similarities in the goofiness and in their eyes and facial expression. There is practically no other way to look at it and you are an idiot.

NO! You don't get to make a complete fool out of yourself in a post and keep trying to say you're right and then just forget about it. I want you to know you truly are an idiot and I guarantee this reflects you in real life.
